    In van der Waals' equation of state of the gas law, the constant 'b' is a measure of

    A) intermolecular repulsions

    B) intermolecular attraction

    C) volume occupied by the molecules

    D) intermolecular collisions per unit volume

    Correct Answer: C

    Solution :

    van der Waals' equation for one mole of a gas is\[\left[ P+\frac{a}{{{V}^{2}}} \right][V-b]=RT\] where, b is the volume correction i.e., the volume occupied by the molecules.
